Symantec Endpoint Protection 12.1 has a new and safer mechanism to reset passwords. To reset the password, click the "Forgot your password?" link on the Manager logon screen. The old method for removing passwords has been removed.

That line doesn't exist in the sepm_settings.properties file. I have tried adding it and restarting the SEPM and clicking on the "forgot my password" link and the admin email still goes to a different address.
